The 0.35V max dropout at full load means the input must stay above 3.65V to maintain regulation — a 3.6V lithium cell near end-of-discharge is marginal; a 5V USB rail has comfortable headroom. ## PSRR profile and signal-chain fit PSRR measures 70dB at 10Hz and rolls off to 43dB at 100kHz. This means the regulator attenuates low-frequency ripple from a switching pre-regulator by a factor of ~3000 at 10Hz, but above 10kHz the attenuation drops to ~140x. For an analog front-end sampling at 100kHz, the switching noise at that frequency will pass through unless the upstream converter's ripple is below the ADC's noise floor. Quiescent current is 55µA typical — low enough for always-on sensor nodes drawing microamps in sleep, but not the sub-1µA class needed for coin-cell applications that idle for months. The enable pin lets the system cut the 55µA overhead when the rail is unused. The 4-X2SON package (1x1mm body, 0.5mm pitch) is a compact leadless package with an exposed pad. The thermal pad on the bottom must be soldered to a PCB copper plane to achieve the rated power dissipation — the datasheet's thermal resistance assumes a 1-inch-square copper pad on a 2-layer board. Without that copper area, the junction temperature rises faster at 150mA output. The supplier device package is 4-X2SON (1x1mm), identical to the package / case 4-XDFN Exposed Pad. The enable pin is active-high; leave it floating or tie to VIN for always-on operation. ## Protection and temperature range Built-in protection includes over-current, over-temperature, short-circuit, and under-voltage lockout (UVLO). The UVLO threshold prevents the output from turning on until the input is high enough to keep the pass element in saturation — this avoids brownout conditions on a slowly rising supply rail.","metaTitle":"Texas Instruments TLV71733PDQNT LDO, 3.3V 150mA, 4-X2SON","metaDescription":"Texas Instruments TLV71733PDQNT linear regulator, fixed 3.3V output, 150mA, 55µA quiescent current, PSRR 70dB~43dB, 4-X2SON package, active production, ROHS3","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"PSRR":"70dB ~ 43dB (10Hz ~ 100kHz)","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"4-XDFN Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"150mA","Protection Features":"Over Current, Over Temperature, Short Circuit, Under Voltage Lockout (UVLO)","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 85°C (TJ)","Voltage - Input (Max)":"5.5V","Voltage Dropout (Max)":"0.35V @ 150mA","Supplier Device Package":"4-X2SON (1x1)","Current - Quiescent (Iq)":"55 µA","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.92","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.97000","currency":"USD"},{"qty":10,"price":"$0.86600","currency":"USD"},{"qty":25,"price":"$0.82200","currency":"USD"},{"qty":100,"price":"$0.67530","currency":"USD"},{"qty":250,"price":"$0.63128","currency":"USD"},{"qty":500,"price":"$0.55788","currency":"USD"},{"qty":1250,"price":"$0.44043","currency":"USD"},{"qty":2500,"price":"$0.41550","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a1b62b2c012289dfda1410b8d5c4eaea.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the PSRR of TLV71733PDQNT at 100kHz?","answer":"PSRR is 43dB at 100kHz, rolling off from 70dB at 10Hz.
